The POLARBEAR experiment achieved first light in Chile on January 10th, 2012 with observations of Saturn.
Below we show signals from two polarization-sensitive detectors in one array pixel. To the right, the 1284-bolometer array is being installed. At the bottom, a beam map from Jupiter is shown.
The team is currently preparing the system for science observations in April, when weather conditions in Chile become suitable.
